Brake Rotor & Steering Box replacement - PeachParts Mercedes-Benz Forum

#1 05-16-2002, 04:23 PM

I have an '83 300D and I am in the process of putting it back on the road after sitting for 1 1/2 years. I started with dropping the oil and changing the filter and both the fuel filters as well. Any advice on this would be great!

I need to pull the brake rotors off and slap on new ones. I've done the pads before, but looking at the rotors, I don't see any obvious signs on pulling them off. Maybe I am just inempt at seeing the obvious, but I need advice on doing this.

Also, gone through 1 used and 1 rebuild steering box and still have about 4-6 inches of play in the wheel. The box is old now (4-5 years), but this is the way it was when new (about 2-3 inches of play vs. 4-6 inches now). I am assuming I will need to replace it with a new one. The last I remember a mechanic (non M-B one) told me the the front end looked ok. The springs and shocks were replaced about 4 years ago, front and rear.

Please advice.

You need to pull the rotor & hub assembly off by pulling the spindle nut & bearings. The rotor is held onto the hub from
the backside by allen bolts.
I put the assembly back onto the tire/wheel and leaned it against
a wall in order to get enough "oomph" to loosen the bolts.

The rears come off with a nice little blow w/ a hammer. The fronts however I believe come off by removing the outer bearing cover plate & w/ a 5mm allen loosen the "set" screw and pull the bigger bolt & voila ??? !

Thanks for your input. BIGMIKE, sounds like a lot more trouble than it's worth, yes? I am just picturing myself with car, rotor/hub assembly, walls behind me ... Maybe, beter to let a shop handle it? I HATE to just say that... let a shop handle it. Usually, that means to grease your interior, over charge you and do a messed up job anyway.
I gotta' get myself the books for this car.
Heck, I think I'll give it a go.

Don't worry Potomac, I'll be ready with the hammer as well. Now, THAT'S my style !! (not really, I'm good to my baby).

It's realy not too bad.
I assumed you were talking about the front rotors, and that
your car is the same as my 126.
The remounting on the tire trick I learned here on another thread,
I wish I could remember who posted it to give proper credit.
It really just makes the job much easier than trying to get enough
torque on the bolts while the rotor/hub is spinning in your lap.
Repack the bearings before reassembly.

Where are you on the Island? I'm in Holbrook (Suffolk).
